php代码:

<?php
/*
 * static
 */

 /*静态:属于类而不属于单个对象 (全局的,所有对象共享的)
  *静态属性:类的方法内调用静态属性时,不要使用$this->方式,而要使用self::的方式
  *静态方法:
  *在类没有任何对象的时候也能被调用
  *当成普通方法来用也没问题的
  *在静态方法中不能调用普通方法
  * 
  * */
 class xin {
 	static private $name;
 	public function setname($namec) {
 		self::$name = $namec;
 	}
 	
 	public function getname() {
 		return self::$name;
 	}
 	
 	static public function name($namecc) {
 		echo "I am $namecc";
 	}
 }
 
 $xind = new xin();
 $xind->setname("地方 <br/>");
 echo $xind->getname();
 
 $oldd = new xin();

 echo $oldd->getname();
